ASP script error 500 Internal Server Error - URGENT repair needed

I have my form here - [login to view URL] Please test it and tell me if you get this error: 500 Internal Server Error The server encountered a script or configuration error while trying to provide the page you requested. Please try again later. The form is going to the database but the person is getting the error message below and is not able to upload photo an dis not being redirected to the payment page. I need this fixing asap, the quicker the better. For the skllled asp expert this will be a very quick repair. I can pay upto $20 maximum. I have contacted the host company and this is their reply - I have tested .asp scripting ([login to view URL]) on your website and the feature works correctly on your hosting package. I have also loaded the contact form in my browser and did not receive the error message. I am afraid this may be an intermittent issue generated by the code used for the contact form so I would kindly recommend contacting a web developer as they will be able to point out specific errors.
